If I had to describe this forecast period in just a few words I would have to use words like high pressure, dry and mild. According to the weather models, it looks like we are in for some unique weather over the next seven to 10 days. I use the word unique because I have not seen this type of weather pattern in the winter that often.

The weather for this period looks like it will be dominated by a large area of high pressure sitting over the western half of North America. This ridge of high pressure will either keep most of the Pacific storms at bay or force them to go well to our north. Over the eastern half of North America, low pressure will dominate. So, in your mind’s eye, picture the jet stream running overtop of the western ridge of high pressure, then diving southeast, curving around the bottom of the eastern trough of low pressure.

This places Manitoba fairly close to the dividing line between the high and low pressures. Currently it looks like pretty much all of agricultural Manitoba will stay on the south side of this line, meaning plenty of sunshine and mild temperatures. Every three to four days we can expect weak areas of low pressure to ripple down the dividing line and bring with them the chance of some flurries, but overall it looks like it will be dry.

Since we are close to the dividing line between two significantly different weather regimes, we have to keep in mind that it won’t take a huge shift in the pattern to make us either colder and snowier or possibly even warmer with highs routinely pushing the top end of the usual temperature range.

Usual temperature range for this period: Highs: -14 to 0C. Lows: -25 to -8C.
